A material's half-value layer (HVL), or half-value thickness, is the thickness of the material at which the intensity of radiation entering it is reduced by one half. HVL can also be expressed in terms of air kerma rate (AKR), rather than intensity: the half-value layer is the thickness of specified material that, "attenuates the beam of radiation to an extent such that the AKR is reduced to one-half of its original value. In this definition the contribution of all scattered radiation, other than an… WebHVL 2 The required thickness of the shielding can then be calculated by multiplying n by the relevant TVL or HVL value, i.e. thickness ( ) TVL or HVL.tn n=× × (5.1) The TVL and HVL will decrease with increasing x-ray energy and n will need to be increased to achieve a specific dose rate on the exterior of the shielding for a given incident ...
